Node.js acl + mongoose, Cannot read property 'collection' of undefined

I am using node_acl (https://github.com/OptimalBits/node_acl), I initialized acl like this:

var mongoose = require('mongoose');
var acl = require('acl');

mongoose.connect(mainConfig.mongodbUrl, function(err, db){
    if(!err){
        acl = new acl(new acl.mongodbBackend(db, 'acl_'));
        acl.allow('guest', 'business', 'view');
    }
});

and got error:

   Unhandled rejection TypeError: Cannot read property 'collection' of undefined

The mongoose connect method does not give a second parameter. To get the db needed for the acl module, you need to get it directly from the mongoose instance.

mongoose.connect(mainConfig.mongodbUrl, function(err){
    if(!err){
        acl = new acl(new acl.mongodbBackend(mongoose.connection.db, 'acl_'));
        acl.allow('guest', 'business', 'view');
    }
});
